Abstract
The utility model belongs to the die manufacture technical field, in particular to a powder metallurgy die. The technical proposal of the utility model is that the powder metallurgy die comprises a die sleeve and a cavity block positioned in the die sleeve, wherein, the cavity block includes an upper cavity block and a lower cavity block, a lug boss is arranged between the upper cavity block and the lower cavity block, and the upper cavity block is connected with the lower cavity block through positioning pins. The powder metallurgy die has the advantages of simple processing method, high precision and good finish quality.
Description
Technical field
The utility model belongs to the technology of die manufacturing field, relates in particular to a kind of powder metallurgy die.
Background technology
In the powder metallurgy process, some product tape one convex, and the width of convex has only several millimeters, even it is narrower, can not make a drift separately,, lean on the unsteady shaping of former so this convex can only be made on the former, with the convex on this former of spark machined, but size is difficult to control, and the fineness of die wall is very poor, and the pressed compact knockout press can strengthen, product surface is coarse, low precision.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of powder metallurgy die is provided, and this die processing method is simple, the precision that manufactures a product height, and fineness is good.
For solving the problems of the technologies described above, the technical solution of the utility model is: powder metallurgy die, comprise die sleeve and the former that is positioned at die sleeve inside, described former comprises former and following former two parts, described going up between former and the following former has a convex, and last former is connected by alignment pin with following former.
There is a step at the place of being connected between die sleeve described in the utility model and the former.Because product is shaped as convex on former, former is stressed, so there is a step former and die sleeve cooperation place, prevents from that former is stressed to deviate from die sleeve.
The beneficial effects of the utility model are: powder metallurgy die, comprise die sleeve and the former that is positioned at die sleeve inside, described former comprises former and following former two parts, and described going up between former and the following former has a convex, and last former is connected by alignment pin with following former.After changing the mould that edge pieces together into by the former of former one, determine the position of module up and down by alignment pin, the manufacture difficulty of mould can reduce, and precision can improve.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Among the figure: 1-die sleeve, the last former of 2-, 3-alignment pin, 4-convex, former under the 5-, 6-step.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The specific embodiment
According to shown in Figure 1, powder metallurgy die, comprise die sleeve 1 and the former that is positioned at die sleeve 1 inside, described former comprises former 2 and following former 5 two parts, described going up between former 2 and the following former 5 has a convex 4, last former 2 is connected by alignment pin 3 with following former 5, and there is a step 6 at the place of being connected between die sleeve 1 and the former.
Claims (2)
1. powder metallurgy die comprises die sleeve and the former that is positioned at die sleeve inside, and it is characterized in that: described former comprises former and following former two parts, and described going up between former and the following former has a convex, and last former is connected by alignment pin with following former.
2. powder metallurgy die according to claim 1 is characterized in that: there is a step at the place of being connected between described die sleeve and the former.
